Polyether L-42 is a low-toxicity, safe nonionic surfactant with no significant harm to human health, environmentally friendly and easily biodegradable.
Detailed Description
Polyether L-42 (Poloxamer 122) is a high molecular weight polyoxypropylene-polyoxyethylene block copolymer ether. According to the United Nations' Globally Harmonized System of Classification and Labelling of Chemicals (GHS) classification criteria, this product is not classified as a health hazard or environmental hazard substance. Its acute toxicity, skin corrosion/irritation, serious eye damage/eye irritation, respiratory or skin sensitization, germ cell mutagenicity, carcinogenicity, reproductive toxicity and other toxicological endpoints do not meet the classification criteria, demonstrating excellent overall safety performance.
From an environmental perspective, Polyether L-42 has good biodegradability, no bioaccumulation potential (Log Pow < 3), and exhibits low toxicity to aquatic organisms, meeting ecological safety requirements. This means that the product can be gradually decomposed by microorganisms in the natural environment, will not accumulate in the food chain over the long term, and has a relatively small impact on the aquatic ecosystem.
In terms of transportation and storage, Polyether L-42 is classified as a non-hazardous substance under current regulations, with a closed-cup flash point above 200°C. It is not a flammable liquid, has no explosive properties, and is not an oxidizing agent, posing very low safety risks under normal use conditions.
Safe Handling Recommendations
Although the product itself is highly safe, Guoli Chemical still recommends following the following basic protective measures in industrial operations:
- Wear chemical safety goggles and protective gloves when handling, and wear appropriate work clothing to avoid prolonged skin and eye contact.
- Ensure good ventilation at the work site, using local exhaust or general ventilation to prevent aerosol accumulation.
- Wash hands thoroughly after handling. Contaminated clothing must be cleaned before reuse.
- Follow good industrial hygiene practices. Eating, drinking, smoking, and storing food are prohibited in the workplace.
First Aid Measures
- Skin contact: Immediately remove contaminated clothing and thoroughly rinse skin with plenty of soap and flowing lukewarm water. If irritation persists, seek medical advice.
- Eye contact: Immediately flush eyes with plenty of flowing clean water or saline for at least 15 minutes, holding eyelids open. If wearing contact lenses, remove them and continue flushing, then seek immediate medical attention.
- Inhalation: Immediately move the person to fresh air and maintain an open airway. If respiratory discomfort or persistent cough occurs, seek medical attention immediately.
- Ingestion: Rinse mouth with water. Do NOT induce vomiting. Seek immediate medical attention and show the product container or safety data sheet.
Environmental Spill Management
- Small spills: Absorb with inert absorbent material (e.g., sand, vermiculite, universal absorbent pad) and sweep into a closed container. Dispose of waste in accordance with local regulations.
- Large spills: Quickly evacuate personnel to a safe area, contain the spill to prevent entry into sewers, waterways, or low-lying areas. Use explosion-proof tools to collect and transfer to a spare container for recovery or disposal.
